Verifying the configuration
# Initiate a connection between Switch A and Switch B to trigger IKE negotiation. After IPsec SAs are
successfully negotiated by IKE, the traffic between the two switches is IPsec protected.
Main mode IKE with pre-shared key authentication
configuration example
Network requirements
As shown in Figure 97, configure an IKE-based IPsec tunnel between Switch A and Switch B to
secure the communication between the switches.
• Configure the two switches to use the default IKE proposal for the IKE negotiation.
• Configure the two switches to use the pre-shared key authentication method for the IKE
negotiation.
